Acid Proof Bricks
Description
Acid Proof Brick is an anti-corrosion and acid-resistant material made of quartz, feldspar and clay as the main raw materials and fired at high temperature.
Features
- High acid resistance, low water absorption, good flatness; beautiful and generous, elegant style.
- It has the properties of impermeability, frost resistance, salt resistance, alkali resistance, and weak acid corrosion resistance, and has strong bonding force with various materials.
- It can be applied on the surface of wet substrate without drying, and can be hardened in wet environment or under water.
- It is easy to operate and construct, similar to ordinary cement mortar construction, and easy to clean.
